Design of a coaxial window for high power CW magnetron

Abstract

For a coaxial window of 2450 MHz, 60 kW magnetron, there are mainly two main requirements. One of the requirements is its low reflection coefficient at 2450 MHz operating frequency, the other is its handling capacity of more than 60 kW CW power. This paper is to establish initial design methods using the transmission line theory for such a coaxial window, then analyzing the voltage breakdown and the overheating problem.
